I found that spectrum of struct vis_chunk, but it only is current, how to get the spectrum of whole file?


In addition, I read the source code of foo_bitcompare, it call audio_chunk_i.get_data to get src1, what is this?

Could you give me some advice? I want to draw the waveform of whole audio file, just like audacity.

That's not possible as foobar2000 only decodes the current playing part of the file - not the entire file before playback.

It has been discussed before and I think it's a really good idea, but you need to create a separate scanner, similar to the replaygain scanner and store the image somewhere.

If you do this, it would be cool if you were also able to create a CUI seekbar as discussed in the other thread

Thanks. I read that topic, and realized that it is a challenge. I will read more audacity and think...
